Two finite-length sequences x 1 [n] and x 2 [n], which are zero outside the interval 0

Question:

Two finite-length sequences x₁[n] and x₂[n], which are zero outside the interval 0 ? n ? 99, are circularly convolved to form a new sequence y[n]; i.e.,

If, in fact, x₁[n] is nonzero only for 10 ? n ? 39, determine the set of values of n for which y[n] is guaranteed to be identical to the linear convolution of x₁[n] and x₂[n].
